The count not only including directories but also the files "attrib". One in
each directory.
I believe your counting (19491 Total files, 10 regular files) can't be
correct. Regular files must be an odd number because count of directories
and attrib files must be an even number.

You can do a "ls -R /var/lib/backuppc/pc/<yourhost>/<backupnumber>"
